Measurement of Ilex No 5 Shutter?

I just got a Kodak 305 in an Ilex No 5 shutter and would like to know if anyone can tell me the inner diameter of the shutter so I can go ahead and cut the hole in my lens board and have it ready to mount when it arrives?

Re: Measurement of Ilex No 5 Shutter?

Knowing that the OP earlier was looking for a Kodak 305mm Portrait lens i made the assumption that he had found one.
The 305 portrait lens have an f4.8 in shutter and f4.5 in barrel so it needs a #5 shutter.

Ah! Hey Jan, I thought you were going to send me your lenses for safekeeping from the motorcycle gangs?;-) For future reference should anyone wonder, the #4 Kodak is larger than a standard #4. The flange thread is 2.735 vs 2.5.

Re: Measurement of Ilex No 5 Shutter?

The outer lip diameter of the flange for the #5 Universal my 305mm Kodak Portrait is in measures 85.3mm.

I'm curious, is this the same flange as an Ilex #5 for certain? My shutter is self cocking, M/X/OFF synch with bipost, and is labelled "NO. 5 UNIVERSAL SYNCHRO SHUTTER" "EASTMAN KODAK COMPANY, ROCHESTER, N.Y.", I don't see an Ilex marking on it anywhere though I presume they made it.

Re: Measurement of Ilex No 5 Shutter?

Here's a data point: I have two Kodak No 5 Universal Synchro Shutters. I don't know if either flange is original. The first shutter measures 3.197"-3.234" (81.20-82.15mm), the second 3.200"-3.224" (81.27-81.89MM).
